“These are primitive beginnings in art, such as one usually finds in ethnographic collections or at home in one's nursery. Do not laugh, reader! Children also have artistic ability, and there is wisdom in their having it! The more helpless they are, the more instructive are the examples they furnish us; and they must be preserved from corruption at an early age. Parallel phenomena are provided by the works of the mentally diseased; neither childish behaviour nor madness are insulting words here, as they commonly are. All this is to be taken very seriously, more seriously than all the public galleries, when it comes to reforming today's art.”

Introduction
Idea for a Universal History from a Cosmopolitan Point of View (1784)
Context: Since men in their endeavors behave, on the whole, not just instinctively, like the brutes, nor yet like rational citizens of the world according to some agreed-on plan, no history of man conceived according to a plan seems to be possible, as it might be possible to have such a history of bees or beavers. One cannot suppress a certain indignation when one sees men’s actions on the great world-stage and finds, beside the wisdom that appears here and there among individuals, everything in the large woven together from folly, childish vanity, even from childish malice and destructiveness. In the end, one does not know what to think of the human race, so conceited in its gifts.

How the Self Controls Its Brain (1994)
Context: The more we discover scientifically about the brain the more clearly do we distinguish between the brain events and the mental phenomena and the more wonderful do the mental phenomena become. Promissory materialism is simply a superstition held by dogmatic materialists. It has all the features of a Messianic prophecy, with the promise of a future freed of all problems—a kind of Nirvana for our unfortunate successors.

Opening lines
The Napoleon of Notting Hill (1904)
Context: The human race, to which so many of my readers belong, has been playing at children’s games from the beginning, and will probably do it till the end, which is a nuisance for the few people who grow up. And one of the games to which it is most attached is called “Keep to-morrow dark,” and which is also named (by the rustics in Shropshire, I have no doubt) “Cheat the Prophet.” The players listen very carefully and respectfully to all that the clever men have to say about what is to happen in the next generation. The players then wait until all the clever men are dead, and bury them nicely. They then go and do something else. That is all. For a race of simple tastes, however, it is great fun.
For human beings, being children, have the childish wilfulness and the childish secrecy. And they never have from the beginning of the world done what the wise men have seen to be inevitable.
